Why Choose the Lovato ME024RSD024 Electronic Reversing Starter?
The Lovato ME024RSD024 is a compact electronic reversing motor starter with integrated STO (Safe Torque Off), designed to provide forward/reverse motor control, electronic switching and motor thermal protection in a single device. It has a rated operational current of 2.4 A AC-3 / AC-53a and supports operational voltages from 40–500 V AC.
Unlike conventional reversing arrangements that require multiple electromechanical contactors and interlocking components, the ME024RSD024 integrates the reversing function electronically. Its built-in Class 10A thermal motor protection has an adjustable trip range of 0.18–2.4 A, allowing the starter to be configured for the rated current of the connected motor.
For safety-related machine applications, the ME024RSD024 incorporates a Safe Torque Off (STO) function rated to SIL 3 according to IEC 61508 and Performance Level e according to ISO 13849-1. A 24 V DC auxiliary and control supply, diagnostic outputs and compact construction make it a versatile solution for modern industrial automation and machine-control systems.

Integrated Reversing, Motor Protection and Functional Safety
The ME024RSD024 combines several functions traditionally implemented using separate motor-control components. Electronic forward/reverse switching provides the reversing function, while the integrated Class 10A thermal protection monitors the motor load and can be adjusted from 0.18–2.4 A to suit the connected motor.
Its integrated STO safety function provides a means of preventing torque generation when correctly incorporated into the machine safety system. With safety capability up to SIL 3 and PL e, the ME024RSD024 is particularly suited to modern machinery where compact motor control and safety-related stopping functions need to be coordinated within the automation architecture.
Typical Applications
- Forward/reverse control of three-phase motors.
- Conveyors requiring bidirectional movement.
- Material-handling and positioning machinery.
- Packaging and production equipment.
- Automated machinery requiring integrated STO functionality.
- Compact industrial control panels and OEM machine assemblies.
